DSL extractors to extract response effective size

[j4cqui]

Please describe your feature request:

Can you add the possibility to see the size of the response.

Web server doesn't always send the Content-Length header, and that can be a great improvement to have the size of the response.

Describe the use case of this feature:

When you are using some templates to dump information, which can be useful to see which one is dumping the largest or not only one information. Or when you are working on large scope to prioritize certain assets.

The response size (calculated on the effective body length) is already available among the matchers. Hence it's already possible to filter out the assets according to any specific logic. For a quick flyover of the targets, probably httpx would be a better option.
Todo:

• Ensure length can be used among extractors

@j4cqui now you can do with using newly added DSL extractors:

    extractors:
      - type: dsl
        dsl:
          - "len(body)"
